Mechanisms- in context
For example, in biology the anti-ID mechanism is "culled genetic accidents". In contrast the ID position which posits there was a plan, a structure, a purpose, an intention- IOW some grand (or not so grand) design.
Many of the greatest scientists who ever graced this planet used science as a way to understand that design. IOW for those who embrace ID they can only be as scientifically literate as those great scientists. Which is something I would wish on everyone.
OK mechanisms are a way of doing things. We can do things by design or we can do things willy-nilly. Both are mechanisms in this sense- the sense that the word is being used in this debate.
